Abstract (en)
[origin: WO2013055442A1] The disclosed embodiments provide a battery cell. The battery cell includes a cathode current collector containing graphene, a cathode active material, an electrolyte, an anode active material, and an anode current collector. The graphene may reduce the manufacturing cost and/or increase the energy density of the battery cell.
